Hmm, on my RaQ2, the Linux kernel shows the following lines:
>> eth0: Digital DS21143 Tulip rev 65 at 0x10100000, 00:10:E0:xx:xx:xx, IRQ 4.

Could you see any info about chip revision and device address
like the above?
BTW, according to Linux cobalttulip_raq.c,
"eth0: Old format EEPROM on Cobalt 27 board." message
would not be printed if the chip is DC21041:

So I'm confused a bit.. (I should check other sources for 2700?)
